iPhone 3GS

Products Reviewed

In slightly less than two years, Apple’s iPhone has transformed how the world thinks of cellphones. Phone companies and hardware-makers alike have rushed to ape the iPhone’s touchscreen interface, easy access to the Internet, and bustling App Store. The iPhone is no longer the mind-blowing, category-busting product it was in the summer of 2007. Our minds have been blown, the category was busted, and now competitors such as Palm, Google, Nokia, and Research in Motion are fighting back.

Yes, the competition is much closer to Apple now than it was two years ago. But the iPhone 3GS makes it clear: Apple is still leading the pack, in most cases by a wide margin.

The S is for “same”

Externally, Apple hasn’t messed with success—the iPhone 3GS is almost completely indistinguishable from the original iPhone 3G model, which itself was remarkably similar to the original iPhone. Front and center is the iPhone’s signature feature: a bright, beautiful high-resolution 3.5-inch diagonal touchscreen, offering a resolution of 480-by-320 pixels. The iPhone 3GS has Apple’s usual complement of four physical buttons (Home just below the touchscreen, sleep/wake up top, a volume up/down rocker on the left side, and a ringer toggle just above the volume controls) and the same black or white plastic back shell introduced with the iPhone 3G.

If you need to know which model is which, there’s only one clear way to do so: Look at the lettering on the back of the phone. If it’s in the same silver ink as the Apple logo, it’s an iPhone 3GS. (Likewise, if 32GB appears below the word iPhone, you know it’s an iPhone 3GS—the previous model was only available in 8 GB and 16 GB editions, while this phone’s capacities have doubled to an impressive 16 GB and 32 GB, allowing users to load their phones up with even more apps, tunes, and videos.)

Beyond the color-matched lettering, which shows a uniquely Apple-like attention to detail, the only other change to the outside of the device is the addition of an oleophobic coating to the device’s touchscreen. When Apple designed the iPhone to be controlled entirely by touch, the company has had to deal with the unpleasant reality that human beings tend to secrete oil from their pores, as well as stick their fingers in greasy foodstuffs from time to time. The iPhone 3GS’s screen coating is intended to keep fingerprints to a minimum.

I’ve never really found fingerprints to be a major problem with the iPhone, since the device’s screen has always been quite bright. But it’s undeniable that in the right lighting conditions, fingerprints can really get in the way—especially when you’re trying to watch a video.

The iPhone 3Gs’s oleophobic coating doesn’t make your fingerprints magically fade away. What it does is create an oil-repellant surface that’s easily wiped clean. When I handled an iPhone 3G and an iPhone 3GS with similarly oily hands—olive oil, if you must know, from a pizza I was making—I was rapidly able to dump my grubby prints all over both devices’ touchscreens. After I rubbed the iPhone 3GS screen onto my t-shirt’s right sleeve, it was perfectly clear. In contrast, rubbing the iPhone 3G’s screen on my t-shirt’s left sleeve seemed to leave a thin film of oily residue spread uniformly across the entire surface, rendering everything a bit hazy.

Will people buy the iPhone 3GS because it’s got an oil-repellant screen coating? Certainly not. But in adding the coating, Apple combats a weakness—albeit minor—in the design of the iPhone. Given how few changes Apple made to the iPhone’s exterior, this is clearly a company that feels great confidence in its current product designs. Instead of revamping the phone’s look and feel, the company’s designers are instead focused on the little things, like making it easy to wipe off greasy fingerprints.

That said, I have to point out that many iPhone users choose to protect their iPhone’s screen from hazards more noxious than oil by using some sort of screen protector. When you see those people on the street, whatever you do, don’t say the word oleophobic. It will just remind them that this is one feature they’ll have no use for.

The S is for “speed”

The lack of external changes belie what’s going on underneath the iPhone 3GS’s glass and plastic exterior. The iPhone’s last upgrade added a faster cellular radio and a GPS chip, but otherwise, the iPhone 3G’s internals were largely unchanged from the original iPhone. The iPhone 3GS, on the other hand, is a major step forward in terms of the iPhone’s technological underpinnings. Its processor runs at 600 MHz, compared to previous models’ 412MHz. It’s got 256MB of RAM, compared to 128MB in previous models.

The result is an indisputably faster device, not just at some tasks, but at every task. The iPhone 3GS booted faster than any other iPhone OS-based device, and launched every app I tried in record time. Its Safari browser had the dramatically fastest JavaScript engine as measured by the SunSpider benchmark, and loaded Web pages dramatically faster as well. Every aspect of using the phone felt noticeably faster on the iPhone 3GS than on the iPhone 3G. Even actions that only took moments before now happen instantaneously.

While you’ll notice how responsive the iPhone 3GS is thanks to its increased processor speed, the programmers who develop your favorite apps will appreciate the large amount of RAM. The more memory that’s available for iPhone apps, the faster and more stable they will be. Numerous iPhone developers complained about the extremely tight memory conditions in previous iPhone OS devices, which led to slowdowns and plenty of app crashes. With the iPhone 3GS, those apps have twice as much room to breathe. The result should be a faster and more stable system.

The speed doesn’t stop with app launches and fast-loading Web pages, either. The iPhone 3GS supports the new OpenGL ES 2.0 standard, meaning that a slew of iPhone game apps will be able to capitalize on advanced graphics features to create higher-quality graphics than have been seen on the iPhone up to now. But more important, the iPhone 3GS is just better when it comes to graphics. Games that featured jerky, low-frame-rate gameplay on the original iPhone and iPhone 3G—we’re looking at you, Crash Bandicoot Nitro Kart 3D—spring to life on the iPhone 3GS with high frame rates and smooth motion. The end result: old games will get new life, and the new games to come will blow away anything you’ve seen so far on the iPhone platform. Sony and Nintendo, be warned.

The last component of the iPhone 3GS’s speed is, of course, the speed of the cellular network. Here, Apple’s integrated a new cellular radio that supports the 7.2 Mbps HSDPA specification. Basically, what that means is that the iPhone 3GS will support a new generation of cellular technology that will offer dramatically fast download speeds—once AT&T builds the network to support it. AT&T says it’ll start rolling out that network this fall, but it’ll be a lot longer before it’s widely available. So perhaps it’s safe to say that while your iPhone 3GS won’t seem any faster that previous models on today’s cell networks, it’s got room to grow that the other phones simply don’t have. Now it’s up to AT&T to deliver on that promise.

The S is for “snapshots”

The original iPhone included a mediocre 2-megapixel still camera. As I said in my review two years ago, “It doesn’t zoom and doesn’t work well in low light, but with still subjects in well-lit areas it produces nice results. It’s definitely more appropriate for fun shots when no other camera is around, [rather] than as a replacement for your digital camera, even if your camera is five years old.”

The iPhone 3G didn’t improve matters a whit, using the same camera as its predecessor. Quoting myself again, from last year’s iPhone 3G review: “For a product as on the cutting edge as the iPhone, its built-in camera is an embarrassment. Like the camera on the original iPhone, it’s got a basic two-megapixel resolution, doesn’t zoom, has no flash, doesn’t work well in low light, and doesn’t take videos. With still subjects in well-lit areas it produces nice results. In terms of quality, the consumer point-and-shoot digital camera I bought seven years ago still blows it away, and most of the iPhone’s smart phone competitors offer better cameras as well.”

The iPhone 3GS finally addresses perhaps the iPhone’s weakest feature, upgrading the camera to a 3-megapixel model (still not exactly earth-shattering in terms of resolution). It still won’t zoom or flash, and the low-light images it produces are better, but still not great. Still, there’s no denying that this new camera is an improvement on the original. In general I found the images from the iPhone 3GS to be clearer, with brighter colors and sharper definition.

A still photo from the iPhone 3GS camera (left) definitely shows more detail and offers better quality than a still from the iPhone 3G (right).

Aiding the iPhone 3GS camera’s output is the ability to focus, which the previous iPhone camera lacked. By default the camera auto-focuses on the scene you’re shooting, though you can tap on the touchscreen to make it focus on a particular object. If that object is in a darker or lighter area of the frame, the camera will also adjust to make sure that location is properly exposed, even if that means other areas of the frame will be blown out or left in darkness. The focus isn’t exactly quick, but it does work, and the resulting images are definitely sharper than in previous models.

The new camera also allows you to take pictures of close-up objects—a test that previous iPhone cameras utterly failed. Not only is this exciting for people who want to e-mail a shot of a newspaper or magazine page or a close-up of one of their kids’ toys, but it opens up the possibility that the iPhone 3GS can actually function as a barcode reader for the first time, now that it can snap images of barcodes with clarity. (In many countries grabbing a bar code with your cell phone in order to get more information about a product on a billboard or in a magazine has become a somewhat common activity; personal-inventory apps such as Delicious Library could also benefit from integration with the new camera.)

This extreme close-up shows the dramatic improvement in macro shots on the iPhone 3GS's camera (bottom) compared to the one on the iPhone 3G (top).

Then there’s the big news with this new iPhone camera: it shoots video. It’s real video, too—not high-definition, granted, but full standard-def video. To shoot video, you flip the Camera app into video mode by touching a small switch in the corner of the screen and press the big red button. Once you hear a chime and see a time code begin to count upward from zero, you’re recording video.

I compared the video the iPhone 3GS shot to the video from my point-and-shoot camera, a Canon PowerShot SD700 IS. The iPhone’s video is much softer than the PowerShot’s, making it pleasant to look at but fairly lacking in detail. However, the audio recorded by the iPhone 3GS was excellent, far better than the (frankly awful) quality of the PowerShot.

I asked our Christopher Breen to test the iPhone 3GS against his Flip Ultra, the popular pocket standard-definition camcorder. His results were much the same, with the iPhone 3GS's video being much softer than the Ultra's, with bright portions of the image easily blown out in the sunlight. In addition, the Flip Ultra proved to have much superior audio than the iPhone 3GS.

These video stills show that the Flip Ultra (bottom) offers much more detail than the iPhone 3GS (top).

Bottom line: the iPhone 3GS shoots decent, albeit somewhat soft, standard-def video. It’s great for shooting video when your iPhone’s the only device you’ve got with you. If you want better-quality video, you probably want a dedicated video camera, ideally one that can shoot in high definition.

The new photo/video interface displays videos with an icon and video length; the filtering buttons at top are only available via the Camera app.Once you’re done shooting your video, the iPhone 3GS stores them within the (now confusingly named) Photos app. Videos appear in the same grid as still images, but with a small strip at the bottom of their thumbnail image with a small movie-camera icon and an indication of how long the clip is.

If you access your Camera Roll by tapping the small thumbnail icon in the bottom-left corner of the Camera app, you’ll see much the same thing, but this alternate view includes a toolbar that lets you display all media, just photos, or just video. (I’m not quite sure why this option is absent from the Photos app itself.)

When you tap on a video, you can choose to play the video or, via a film strip that appears at the top of the screen, trim it by dragging the beginning and end points to different locations. Once you tap the Trim button, the video is trimmed—and as far as I can tell, there’s no going back via an undo or any other means. That’s unfortunate because it means you can’t take a long video, trim a small portion for e-mailing or posting to YouTube, and then retain the longer version for later use. You should be able to undo trims or have the option to duplicate a clip so you can create multiple versions. (And—pie-in-the-sky feature request here—have the ability to attach several clips together to make one mini-movie.)

Once you’ve checked your video and trimmed it if necessary, the Photos app lets you share it with the world by e-mailing it, sending it to MobileMe, or uploading it to YouTube. Uploading was surprisingly fast and easy. And if you’re not a connoisseur of YouTube, no worries—e-mailing videos to Flickr and Vimeo worked like a charm, too.
